Sir Nicholas Soames:To ask the Secretary of State for Defence, what assessment he has made of the sustainability of the Royal Navy fleet in terms of (a) spare parts and (b) missiles.

Harriett Baldwin, Parliamentary Under Secretary of State and Minister for Defence Procurement: The Strategic Defence and Security Review 2015 (SDSR 2015) ensured that investment in capability remained in balance with financial requirements to deliver future Defence commitments. For the Royal Navy (RN), SDSR 15 set out plans for investment in the Queen Elizabeth Class Aircraft Carriers, 19 frigates and destroyers, and further Offshore Patrol Vessels, new tankers and support ships by 2030.

As part of its planning process the RN continues to work alongside other areas of the Ministry of Defence to ensure that all the support and capability programmes are in place to enable it to meet its global operational tasking.
